What is Peter And Alison?
1.
When a person commits a mindless act causing minor damage to another person, for example accidentally hitting someone with a bag. Or a large group of people who cause commotion on public transport systems. People who should not have bothered and it would have been best if they'd stayed at home.
'That woman just broke that mans arm with her trolley'
'Oh what a Peter and Alison'
'PETER, MOVE DOWN THE TRAIN. ALISON PUT THAT BABY DOWN'
